Ru/AgxW(8-x)/6S4 Photocatalyst Synthesized for Hydrothermal Method for Water-Splitting Reaction to Produce Hydrogen under Visible Light irradiation

碩士 === 國立臺灣科技大學 === 材料科學與工程系 === 103 === In this research, a series of photocatalyst AgxW(8-x)/6S4 was prepared through the hydrothermal method by mixing in different proportions of three chemical compounds: CH3COOAg, Na2WO4•2H2O, and CH3CSNH2 as precursors, and then the impregnation method is used...

After the preparation, characterization of prepared photocatalysts was carried out including X-ray diffraction (XRD), UV - Visible spectrometer (UV-Vis), scanning electron microscope (SEM), and energy dispersed spectrometer (EDS). From the result of XRD, it is discovered that as the preparation temperature was 160℃and the proportions was X=2, the photocatalyst AgxW(8-x)/6S4 processes the best crystalline structure. From the result of UV-Vis, it is known as the preparation temperature is 160℃and proportions as X=2, maximum critical wavelength is about 450nm, with the energy gap of about 2.76eV. Furthermore, from the EDS identifications, it is known separately that the actual composition of the photocatalyst is confirmed to be AgxW(8-x)/6S4. Finally, from FE-SEM, it is known that the grain particles of photocatalyst were composing of the spherical structure, and with different preparation temperatures and proportions, the particle diameter sizes also change. From the experimental result, it is known that with the proportion of X=2, at the preparation temperature is 160℃, the photocatalyst AgxW(8-x)/6S4 processes the best reaction activity; and as it is carried with 1wt% co-catalyst of Ru, the hydrogen production rate can reach 62 μmol/g cat/h.
